Applying place templates
When you apply a place template to an existing project, space, or group, you get a preconfigured Activity page that contains the tiles and layout included in the template.
Applying a place template to a place only affects the Activity page in that place. It changes the selection of tiles on the Activity page and the order in which they're displayed.
